SyntaxWarning: Invalid Escape Sequence

[Arszilla]

Hey @Tib3rius,

I have created a provisional Debian package for autorecon - per https://bugs.kali.org/view.php?id=7870. The following files and lines seem to annoy apt, where it displayed a SyntaxWarning highlighting that these lines are using an invalid escape sequence.

• autorecon/default-plugins/bruteforce-ftp.py:11
• autorecon/default-plugins/bruteforce-rdp.py:11
• autorecon/default-plugins/bruteforce-smb.py:11
• autorecon/default-plugins/enum4linux.py:13
• autorecon/default-plugins/lookup-sid.py:11
• autorecon/default-plugins/nbtscan.py:11
• autorecon/default-plugins/nmap-ftp.py:11
• autorecon/default-plugins/nmap-mssql.py:11
• autorecon/default-plugins/nmap-rdp.py:11
• autorecon/default-plugins/nmap-rmi.py:11
• autorecon/default-plugins/nmap-smb.py:11
• autorecon/default-plugins/smb-vuln.py:11
• autorecon/default-plugins/smbclient.py:11
• autorecon/default-plugins/smbmap.py:11
• autorecon/main.py:518
• autorecon/main.py:1238
• autorecon/plugins.py:230
• autorecon/plugins.py:257

Full details below:

This problem can be fixed by using either:

1. A raw string (i.e. r'\s+')
2. Escaping the backslash (i.e. '\\s+')

autorecon has been added to Kali, and Dani has applied a patch to fix this: https://gitlab.com/kalilinux/packages/autorecon/-/commit/0026e00960f7765e1275f450bdafaddb1c186806

I'll leave it open for you to decide on how to address this going forward @Tib3rius :)
